DRIVING-WHEEL CENTER.

Specification of Letters Patent.

Patented June 7, 1921.

Application filed May 4, 1920. Serial No. 378,752.

T 0 all rfa/wm t may concern.: y f

Be it known that we, VILLrAM E. lVooDAnn and HERBERT lV. SNYDER, bothcitizens of the United States, respectively residing at Forest Hills, inthe county oi Queens and State of New York, and Lima, in the county ofAllen and State of Ohio, have invented certain new and usefulimprovements in Drivinglllheel Centers, of which the following is aspeciiication.

This invention relates to driving wheel centers particularly for gearedlocomotives such as the Shay, for example. Considerable difficulty hasbeen experienced in connection with geared locomotives owing to the lackof protection for the rim bolts which secure the gears to the wheelcenters. Then the wheels leave the rails, the ends of the bolts on theinside of the wheel drop on to the rails and the weight tends to eithershear the bolts oil or to bend them.

It is the primary objectof our invention to overcome the aforementioneddiiliculty and we accomplish this, together with such other objects asmay hereinafter appear, by means of a construction which we haveillustrated in preferred form in the accompanying drawings wherein,

Figure l is an end elevation and partial section ot a driver of a. Shaylocomotive vith our improvements applied thereto; and Fig. 2 is a sideelevation of the wheel center shown in Fig. l.

Referring now to the drawings, the reference letter 7 indicates a castdriving wheel center provided with the usual tire 8. The bevel gear 9,through which the wheel is driven is secured to the wheel center bvmeans of rim bolts l0, such bolts being provided with the usual singlenut ll on the outside and the nuts l2 on the inside. The flange of thebevel gear 9 is keyed to the wltieel center 7 as is well understood inthis ar In order to protect the inner end of the bolts l0, we cast aplurality of segmental lugs i3 on the inner face of the wheel center,these lugs being on the rnn of the wheel center and spaced apart asuiiicient distance to permit of the use of the necessary tools fortightening and loosening the nuts l2. llVhen the wheel leaves the railit`will be seen that it will be held un by the lugs 13 instead of comingdown on the rim bolts, and thus the latter are fully protected. This isshown in Fig. l.

le claim:

A driver for gear driven locomotives having means projecting laterallyfromy the inner face thereof for protecting the rim bolts in case oi'derailment.

2. A driver for geared locomotives comprising a driving wheel, a gear, aplurality of rim bolts for securing the gear to the driving wheel andlugs on the rim of the wheel located intermediate rim bolts andextending radially therebeyond.

A driver for geared locomotives comprising a wheel,'a gear therefor,means for attaching the gear to the wheel, and laterally extending meansadapted to take against the rail in case of derailment.

in testimony whereof, we have hereunto signed our names.
